摘要

分析离心机用于研究耐火级二氧化硅颗粒在丙烯酸酯单体混合物中的浓缩悬浮液的沉降。显著稀释或有效颗粒剥蚀的深度取决于沉积时间，并与粒径分布、颗粒体积分数、液体粘度和触变性剂的存在有关。这些分散体的结果与Richardson-Zaki方程一致。讨论了光聚合悬浮液对三维打印的影响。用分析离心机检测了耐火级二氧化硅颗粒在丙烯酸酯单体混合物中的浓缩悬浮液的沉降，以确定稀释深度作为沉降时间的函数，并与颗粒大小、颗粒体积分数、液体粘度和触变剂的存在有关。结果与Richardson-Zaki方程一致。讨论了光聚合悬浮液对三维打印的影响。

Sedimentation of particles in photopolymerizable suspensions

An analytical centrifuge was used to examine the sedimentation of concentrated suspensions of refractory-grade silica particles in acrylate monomer mixtures. Depths for significant dilution or effective particle denudation were determined as a function of sedimentation time, and related to particle size distribution, particle volume fraction, the viscosity of the liquid, and the presence of thixotropic agents. Results for these dispersions are consistent with the Richardson–Zaki equation for hindered settling. The implications on three-dimensional (3D) printing of photopolymerizable suspensions are discussed.
